Scor-Tape

Scor-Tape is a great adhesive. It is a thin double sided tape that comes on a roll with a very thin paper backing for easy tearing (and this is a good thing, so you don't have to use scissors). You can find many knock off brands and I've tried many of them. All will do the job but I will only document my findings with this type of adhesive under the label Scor-Tape to make it easy to find and not confuse new crafters. The knock off brands might have a thicker layer of adhesive, not as easy to tear paper, or perhaps doesn't come in all the useful thicknesses of Scor-Tape. Pricing varies wildly so choose wisely. For my bulk album projects I use a very inexpensive version that only comes in 3 thicknesses, but is thicker and more sticky. It feels more commercial to me. Where for something like a card, I will use the 1/8" Scor-Tape. I try to keep 1/8", 1/4", 1/2", 1" and 2 1/2 " on hand. The wider tapes I use to back paper that I will cut into dies making instant stickers out of the dies. Scor-tape is a thicker adhesive than a similar sticker adhesive applied by a machine called a Xyron Creative Station. If you need super sticky use Scor-Tape to back your die cut paper, if not super sticky will work (such as on a smooth surface), use the Xyron.
